This had only lasted for a few minutes as, impatiently, his hand had slid round, under the gaping blouse to find her bra fastening. I'd watched in almost disbelief at how quickly the fingers had done their job, releasing the bra and urgently pushing it up and away from her pert breasts.
He'd immediately pulled away from her embrace a little so that he could admire her firm breasts, each one tipped by a long, pink nipple standing proud and surrounded by small rings of brown. Almost in slow-motion his hand had crept forward to cup the taut flesh, his finger and thumb closing around the erect nipple. Charlotte's head had shot back and her mouth opened in a silent gasp as she'd felt the electric response from her sensitive nipple. I still hadn't been able to move, hypnotised almost be the sensuality of it all.
His head had now bent down to her bosom, so that his lips and tongue could capture the other nipple and begin to arouse Charlotte even more. For a few confused moments, I'd felt my own nipples responding to the same imagined touch. It had been incredibly confusing for me.
Things had now been getting more urgent as I watched his hand leave her breast, and run quickly down her side, tracing a path around her hips, down her legs and then disappearing under her skirt at her knees. It hadn't stayed there long! Smoothly he'd begun to draw it up the inside of her thigh, lifting her skirt with it until the tops of her tan stockings came into view. He'd paused there for a few seconds whilst his fingers had traced around the bare flesh above her stocking tops. Charlotte arms were now wrapped tightly around his shoulders, her eyes closed as if in pain. I'd suddenly realised that I'd stopped breathing and let out a long gasp myself as I watched him massage the bare flesh of her inner thighs. Charlotte had opened her legs a little to make his exploration that much easier, and my attention had been absolutely riveted on his hand as I watch it rise again, heading inexorably towards her pussy.
As her skirt had lifted higher, I'd seen that she was wearing some matching cream and lacy edged cami-knickers. I'd wondered later if that was intentional on Charlotte's part as the lack of any elastic had made it so easy for his fingers to slip inside the shiny material and begin to move around her pussy. As the fingers had disappeared out of sight I'd only been able to imagine how they must feel as they caressed and explored between her legs. Charlotte's grimace had deepened in response. If I hadn't have known better, I'd have sworn that she really was in pain, but the way that his fingers moved inside the soft knickers didn't look in the least threatening. It had just looked incredibly exciting and I had been dismayed to feel a matching tingle from my own pussy as I'd imagined what those fingers must feel like!
It had seemed that I wasn't the only one getting excited though. With a sudden burst of energy, he'd pulled back, stooping to lift up her skirt and slip and lifting them high so that he could tuck them under her brown belt over her belly. Charlotte's long, stocking clad legs and cream cami-knickers were now fully exposed. I'd had to admit that Charlotte did look gorgeous and sexy. He'd said something to her and she'd smiled, almost shyly. It had obviously been a compliment of some kind.
He'd stopped to kiss her again, his hands at her waist as their lips worked hard at each other. They'd both looked breathless when they'd pulled apart. It had looked as though he'd asked her something, and she'd nodded back urgently. He'd stooped down again as his fingers found the waistband of her knickers and he'd smoothly drawn them down, exposing Charlottes neat little triangle of blonde, curly hair, and the glistening dark slit below it. It was framed neatly by the stockings and suspenders dangling down from her waist.
Suddenly I'd been embarrassed. Surely I had to step away now? But I couldn't and hadn't. I'd become mesmerised by the erotic scene developing in front of me. I may have been blushing as I'd watched him drag the knickers over her ankles, and the tingling between my legs had developed into a pleasant little throbbing, but I could no more move away than stop breathing.
As he'd stood up again, Charlotte's hands had dropped to his waist and begun to unbuckle his belt. His hand had cupped her pussy mound and I'd watched in amazement as his fingers slipped between her wet labia lips and began to wriggle between them. The effect on Charlotte was electric as she simply froze, her hands gripping his belt and throwing her head back again, mouthing words that I couldn't hear. Soon though, her fingers had gone urgently back into action as she'd pulled open his belt, opened some buttons on his fly and started to drag down his trousers.
His white pants had quickly followed suit and I'd watched Charlottes face lighten up as she'd looked down and seen the big erection that she'd released. Her eyes had gone almost animal like as she'd hungrily devoured him, her hand grasping hold of his hot, rigid flesh. I had been getting a bit frustrated at this point because he'd turned his back to me and I'd lost sight of what was now the total focus of Charlotte's heated attention. It had been so annoying!
I hadn't been disappointed for long though. His hand had dipped hastily into one of his pockets before his trousers had descended to his ankles, and come out with a little silver packet. Charlotte had now been almost out of control though as she grabbed the little packet and ripped it open. He'd been laughing I think as she'd pulled out the condom and grasped his cock again. Fortunately for me she'd twisted him round a bit and I'd had a grandstand view as she'd slipped the head of the condom over the tip of his big cock and began to draw it urgently down it's impressive length.
It had all begun to happen fast now as he'd pushed Charlotte back against the workbench, lifting her bottom slightly so that she'd been perched on the edge. She'd dragged her legs out wide, opening her slit even further to welcome him into her, and he'd obliged immediately, standing between her splayed legs and driving his hardness straight into her. Even from outside I'd heard her cry of satisfaction as he'd filled her.
Then he'd slipped his hands around her bottom and he was pulling her back onto him, making sure he'd penetrated her as deeply as he could before his hips had begun to thrust rhythmically back and forward. Charlottes head had dropped onto his shoulder, her arms wrapped around him, but as the thrusts seemed to get became harder and deeper her head went back again, her eyes tightly shut as she concentrated on the heavenly feelings radiating out from between her legs. I knew that my mouth was open as I watched that magnetic scene unfold and I'd had to force my hands to my side as they'd drifted towards the increasingly hot spot between my own legs.
When Charlotte had finally gone rigid, and he'd powered into her for one last time before collapsing against her, I'd stopped breathing again. It was the first time that I'd seen two people having sex, and the emotions that had filled me had been bewildering!
Finally, as their lips had met again, more gently this time, I'd found the willpower to break the spell and turn away from that totally erotic sight. I'd stumbled almost directionless away from the hut, doing my best to rationalise what had been an unforgettably disturbing experience.
-------------------***************----------------
The problem had been that my previous exposure to the pleasures of the flesh had been distinctly limited. At school the other girls had often talked about what they'd done with boys, especially in our senior years, but I'd put a lot of that down to bragging as opportunities in a girls-only school were distinctly limited. Being a bit of a shy soul, and a little scared to experiment, I'd managed to get through school a virgin. I'd had one or two encounters with boys, but nothing had gone beyond the fumbling and groping stage. I'd known all about the biological mechanics of sex, but that didn't make it appeal much in itself and coming from a rather puritan family, I hadn't felt encouraged to explore my boundaries, either with or without a partner!
Now I'd actually watched two people do it! And, ashamed as I'd been at the time, I'd felt excited and my own body had reacted in ways that had been quite unsettling. I'd disguised those feelings by building up some anger. After all, wasn't our French professor abusing his position by making love to one of his pupils? I'd even considered taking the matter to Miss Hendricks, our dour and aged headmistress. But when I'd recalled the look on Charlotte's face as she'd let him make love to her, I'd known deep down that there was no force involved and I'd have had no ally there, probably the opposite! She'd enjoyed every minute of it!
